This reference design is a 120Vac to 5V primary side regulated flyback converter with synchronous rectification on the secondary side. The reference design has extremely low standby power at 67mW. UCC28704 features integrated CC-CV regulation without the use of an optocoupler. PMP20771 utilizes synchronous rectification which improves system efficiency across the designed load range.
